The micrometer and opentelemetry-tracing quickstarts have hardcoded OpenTelemetry Collector image versions in their docker-compose.yaml files:

• micrometer: otel/opentelemetry-collector:0.115.1
• opentelemetry-tracing: otel/opentelemetry-collector:0.89.0

These versions should be updated to use the latest available version (or a consistent recent version across both quickstarts).

Files to update:

• micrometer/docker-compose.yaml
• opentelemetry-tracing/docker-compose.yaml

Note: The version discrepancy between the two quickstarts (0.115.1 vs 0.89.0) also suggests they are not being maintained consistently.
